Internal tourniquet method |
| 摘要 |
An internal tourniquet and method for establishing hemostasis within a portion of a limb to facilitate surgery controls flow of a fluid into a capsule surrounding substantially all of a human joint. Blood concentration in the capsule is sensed; and pressure in the capsule is controlled to maintain a fluid pressure in the capsule within a predetermined pressure tolerance window. The concentration of blood in the capsule is maintained below a predetermined maximum concentration while the fluid pressure is within the pressure tolerance window. |

1. A method of operating an internal tourniquet for controlling hemostasis near a human joint that includes a region through which fluid may be directed to flow, comprising the steps of:
sensing the amount of blood in the region; adjusting the fluid flow rate through the region in response to changes in the amount of blood sensed in the region. |
